To etlichen; it may concern:

Be it lmown that I, HEENAN noma, of Johnstown, in the countyof Comnbrie-ond State of Pennsylvania, have inventf ed e new und 'usefulimprovement in Switch Structures, of which the following is e full,clear, sind exact description, reference being; had to the accompnnyindrawings, which form u part of this specication.

My invention relates to certain new end 4useful improvements in switchstructures,

ond is designed to provide simple and eiiicient means wherebythe urea ofthe supporting surface forthe heel of the tongue 1s increased.

Another object of my invention is to provide a simple and efficientfriction device for the pin or pintle of the tongue.

With these objects in View, my invention consists in the novelconstruction, arrangement, and combination of partsias hereinafterdescribed andvpointed out in the appended claims, reference being had tothe accompanying drawings, in which- Figure l, is a plan View of eportion of a switch structure embodying my invention;

Figs. 2 and 3, are sectional views on the lines lI--l'l ond lll-Hi ofFig. 1 respectively;. Fig, 4, is a plan view of the split bearing forthe tongue pintie,

A., is the switch structure which is provided with the usuel tread undguard surfeces. B is the tongue sont or ioor of the switch structure.

C, is the switch tongue which is provided with the pintle c, having ucountersunlr or conical head c surrounding this pintle, and within erecess l), in the floor of the'switch structure, ure the two portions cend e ot n split bearing, the portion c being semi-circular, and theportion c of rectangula r form. 'ihe diameter of the portion c is equalto the diameter of the rounded por-- tion or heel of the tongue, end thethickness oi" this split bearing is equal to the height of the pintle c.

Below the split bearing, and in the recess D, is e herd metal bearingplate E, and in front of the portion c of the split bearing, end betweenthe tongue C und the plete E is a hey or wedge ll, the object of whichis to clamp the intle between the split beering, sind to hold the toncuein place.

The 'switch .is essem .led as follows Thefplate E is dropped into therecess l), and the tongue with the split bearing surrounding1 the pintleis dropped into its lece. The tongue is clamped down on its ed and thekey F is inserted into the recess D, and driven home through on openingin the side of the structure. The plate E, is then raised so that it isin' Contact with the split` bearing and the head of the piutle, afterwhich the space surrounding the plate is illed with spclter or material'of e like character. The plate can be raised by various methods; eitherby screws projecting through the bottom of the structure, or by Wedgesassing through the orifices in the side of tie structure.

As can readily be seen by reference to the drawings, the aren of thebearing surface for the heel of the tongue is greatly increased bytheuse of the countersunk head of the pintle, and the weer on the pintlecnn be taken u by the use of the split bearing and the we ge. Thisincreased bearing surface .will Greatly prolong the life of u switch,-as it will prevent, what is known to the artes the pounding down theheel of the tongue.

It willbe obvious that various changes may be made in the details ofconstructionbearing being ono line with each other and means for'tightening the bearing.

2. in u swltch structure, a tongue having;

'u pintle with n countersunk head, a split bearing composed of twosemicrcuiur pieces surrounding the ipintle, .e recess in 'the switchstructure to receive the pintie and split bearing, the bottom of thepintie and split bea-ring being on a line with each other and means totighten 'the bearing'.

in a switch structure, a tongue having a pintie, a split bearing'composed of two semicircular pieces surrounding the pintle, a recess inthe switch structure to receive the vpintle :incl split'bearing, tightenthe bearing.

In a switch structure, a tongue having ai pinle with a countersunk head,a. split beau-ing composed of two seniicircular pieces surroimdiug thepintle, e recess in the switch structure to receive the pintle and splithearing, and n wedge to tighten the bearing. In a switch structure, atongue having u pintlc, :i split bearing composed of two seinicireulnrpieces Surrounding the pintle, in the switch structure to receive thepilule und split hearing, the bottoni of the pintle and split bearingbeing on e line Wit and a Wedge to euch other, e hearing plate for thepintle and split bearing in the recess, und means to lighten thebearing. Y,

In n switch structure, :1 tongue having n piutle with a. countersunkheed., :i split hearing composed of two semicircular pieces surroundingthe pint/le, u recess in the switch structure to receive the. pintle andsplit hearing", :i hearing plate for the pintle and splitv bearing inthe recess, and means to tighten the bearing.

7. In a switch structure, a tongue having a pintle, a split bearingcomposed of two semicircular pieces surrounding the intle, a recess inthe vswitch structure te receive the pintle end split bearing, a bearingplate for the pintle and split bearing in the recess,

and e wedge to tighten the bearing.

8.-/In e switch structure, e tongue having a pintle with a. countersunkhead, :L split bearing composed of two semicircular pieces surroundingthe pintle, a recess in the switch structure to receive the pintle andsplit bearing, ai bearing plate for the pintle and split bearing in therecess, and a. ivedgeto tighten the bearing.

In testimony whereof, I have afixed my signature in presence of twoWitnesses.
